GAS-GENERATOR.

Specification of Letters Patent No. 11,714, dated September 26, 1854.

that the same are described and represented in the following specifications and drawings.

T 0 enable other skilled in the art to make and use my improvements I will proceed to describe their construction and use, referring to the drawings in which the same letters indicate like parts in each of the figures.

Figure 1, is a perspective view of the apparatus with my improvements. Flg. 2, 1s

a section of Fig. 1 cut perpendicularly from the line 00, m. Fig. 3, is a section out perpendicularly from the line y, 3 Flg. 4, front elevation of the furnace, with the front wall removed to show the steam generator and heater in its separate flue. Fig. 5 perspective view of the interior of the cooler. Fig. 6 plan of the same. Fig. 7 an enlarged sectional elevation of the steam generator and heater cut perpendicularly through the center.

In the accompanying drawings A is a furnace of brick with a fire space A provided with a grate A and ash pit A There are one or more thin arches A over and across the fire space which support a platform of fire brick B for the gas generating retort B to lie upon, and in a measure protect it from the direct action of the fire, and consequently it lasts much longer. It is made of iron open at eachend and provided with doors B B which are secured to the retort by thebar wedge and bracket B as represented, or screw bolt-s may be used if preferred. The retort B may be partially covered on the sides with fire brick,

which covering may be extended entirely over the top as represented in the drawing if desired.

There is a flue B around and over the retort B opening into the chimney C which is provided with a damper C. The flue B has another flue C leading from it up under the vessel C so as to heat it and the materials in it, from which the gas is to be made, and passes across under said vessel and enters the chimney C as represented; this flue is also provided with a damper C". There is another flue E leading from the fire space A up and around the steam generator and heater E and intothe chimney C; this flue is also provided with a ,dam-

per E The steam generator and heater E consists of two small cylindrical vessels 0. a placed upon the opposite sides of a larger one a which connected at at the bottom and to a at the top as represented.

E is a vessel provided with a cock I) to supply the generator E with water through the siphon pipe I) which conducts the water onto pieces of brick, pumice stone or other refractory or porous substance with which the apartments at and a should be filled as represented in Fig. 3, so as to gradually and regularly convert the water into steam that is introduced into the generator E and prevents it from assuming a globular form and falling to the bottom and forming steam suddenly and produce an undue pressure in the apparatus. The steam generated as above described is heated toa higher .temperature than the retort B and passes into it through the pipe E uniting with and, aiding in generating the gas which may be made of rosin, oil, grease, turpentine", .tar or other substances rich in carbon and hydrogen; at the same time expelling the gas and undecomposed matter fromthe retort through the pipe F into the cooler'F where the undecomposed matter is separated from the gas with facility and without further trouble. The rosin, oil or other material from which the gas is to be made1is put into the vessel C which is heated as heretofore described,so as to melt the same when it passes through the strainer 0 and cock 0' into the pipe 0 which conducts it into the vessel d in the retort B. The vessel d stands upon the block 61, and holds a quantity of the melted matter around the end of the pipe 0 so as to prevent the gas from escaping through said pipe.

The cooler F is a rectangular box made of metal and provided with partitions as represented in Figs. 5 and 6, so arranged that the gas which enters through the pipe F will pass around between the partitions as represented by the arrows and pass out through the pipe F into the gas holder. The cooler F is placed in a bath of water F with sufficient inclination to'run the tar and other condensed matter through the F where it is drawn as. The top of the cooler may be secured by bolts as represented at e or otherwise. p I

The apparatus having been constructed and completed as above described, and the vessel E supplied with water, the vessel C with rosin, oil, or other material from which tfie gas is to be made and fire made upon t e ciently heated the attendant turns the cooks b and 0' so as to supply the requisite quantity of water and melted matter to therespective retorts where the steam and gas is generated and cooled as heretofore described, without coming in contact with water until after it is cooled.

I contemplate that such a number of peep holes may be made in the brick as are necessary to enable the attendant to regulate the heat of different parts as required: and that the apparatus may be modified to 'suit thecircumstances under which it is to be used requiring a particular study for their proper management; and their veryoffensive odor excludes them from dwellings. When made from IOSlll, grease or other materials lntroduced in a liquid state into a'heated retort it is liable to much loss and diflicultyffor if the temperature is allowed to. rise 'above the dull red heat (and it is very difficult to keep it at that temperature) a portion of the gas generated on some part ofthe heated surface is decomposed depriving the gas of some of its illuminating power and carbon which is deposited on the interior of the retort and pipe leading from it so that they are eventually completely clogged. If

grate A When the apparatus is suffiof gasfor illumination For by introducing steam into the gas-. generating retort heated to a higher .temperature than the retort itself I have succeeded in producing more gas from a given quantity of material, possessing greater illu- 'minating power in less time and at a much lower temperature"; which being cooled be fore it comes in contact with waterits illuminating properties become fixed so as to be less affected when brought into contact with water; and besides the retort and apparatus is, notjclogged or choked by its production. In short the result of these improve-.

ments has been the production of a larger quantity of illuminating gas at a much lower temperatureand far less expense and in far less time; from .agiveuquantity of materials which needs no purifying, possessing greater illuminating power, producing a more brilliant v light; without choking or clogging thejr'etorts or apparatus used to make, cool, and convey itj to secure by Letters Patent in the'aboVe'described apparatus for making ga's; is The combination of the'gas generating retort B with thediaphragm steam generating retort a a? chargedwith porous earth pieces of brick, pumice stone or some other orous substance substantially as described.

'or the purposes setforth In testimony whereof ,I have hereunto signed my name.
